My husband’s paternal grandmother had a daughter and 5 sons. His grandfather was a [name]Jr[/name]., and the second of the 5 boys was the III.
Of the 5 boys, 4 had sons, and every one gave his name to his firstborn son. My husband, the elder of two brothers, is a [name]Jr[/name].
Our first son is [name]Peter[/name] [name]Sidney[/name] III, and I love his name He has a second cousin who is a V.
I don’t see any problem with using [name]Jr[/name]. at any time.
There are no rules on names in the US, so whatever you write down on your son’s birth certificate is his name. I am not sure anyone could stop you from naming him [name]John[/name] F [name]Kennedy[/name] XXIII if you were set on it. Traditionally, only a son who has the same name as his father in the same order is a [name]Jr[/name]. The [name]Jr[/name]. distinguishes the two. If the father is [name]Christopher[/name] [name]Richard[/name] [name]Smith[/name] and the son is [name]Christopher[/name] [name]Richard[/name] [name]Michael[/name] [name]Smith[/name], the second middle name distinguishes the son from the father, and there’s no need for a suffix. If the father’s name is [name]Christopher[/name] [name]Richard[/name] [name]Smith[/name] and the son’s name is [name]Christopher[/name] [name]Richard[/name] [name]Smith[/name], and you don’t put [name]Jr[/name]. on the birth certificate, [name]Jr[/name]. is not part of his legal name. They can use Sr. and [name]Jr[/name]. to distinguish themselves–just like the father of a [name]Jr[/name]. with that in his legal name may use Sr., though it isn’t in his legal name–but legally, his name is exactly the same as his father’s. (Not entirely a disadvantage–my husband says that sometimes it can be difficult to deal with a suffix on standardized forms.) Elsewhere I have heard it asked what happens when the Sr. dies–and if the name is on his birth certificate, your son will be a [name]Jr[/name]. for the rest of his life. But if not, he could drop it after his father’s death (or not) and call himself Sr. if he passed the name on again. Another point of interest–some people use a comma before a [name]Jr[/name]., and some do not; my husband does not.
For the record, my husband loves his name and wouldn’t want any other. He does not view himself as an extension of his father, nor does his father view him that way. He is a happy, well-adjusted adult and perfectly capable of surviving on his own (although FIL tries to do more for us than he should, but that’s not so rare). We live next door to my in-laws. Your son should never attempt to change his address from yours at the post office; it will never be straightened out. He should just change his address with any companies he does business with. Your DH will probably need to write Sr. on anything, and at every doctor’s appointment you’ll need to make sure the paperwork is right, among other times. Whenever you get a phone call for [name]Christopher[/name] you’ll have to ask which one. But we also haven’t been able to get a nickname to stick for [name]Peter[/name] III.
I have zero naming regret.
